Applications

The CBW 1206 non-magnetic bondable chip resistor series from SRT Resistor Technology offers a wide resistance range from 10Ω up to 1TΩ, power rating of 0.25W and working voltage rating of 400V, all in a small 1206 package. By utilising SRT’s thick film resistor technology, they are able to offer low tolerances down to ±5.0% (between 10Ω and 100GΩ) as well as a TCR as low as ±50 ppm/°C (between 10Ω and 100MΩ). The CBW 1206 resistor series has the bottom side completely insulated and features AgPd termination for flip chip assembly (face-down, for conductive epoxy assembly) or gold termination for wire bonding (US/TC face up) as well as flip chip (face-down, for conductive epoxy assembly).

The CBW non-magnetic resistor series is also available with an extended high temperature range version (up to +200°C). Please see the separate CBW-HT product pages for further information.

Other sizes and custom tolerance, TCR and VCR options are available upon request. Please contact us for further information and availability.

The below table gives full specifications for each resistor model available including the CBW 1206 series:

¹⁾ TCR: in ppm/K; +25°C…+125°C; TCR below standard TCR (highest value) or value >100G: +25°C…+85°C
²⁾ VCR: typical values, all negative, not available for all TCR values
³⁾ Continuous operating voltage (U_, U_eff): V ≤ √(P*R) or max. working voltage (the lower value)
